Video links for the Times for July 24: A beast on a bike; Super PACs ready for the attack ads

John Steeber Jr. is known as Century John because he never messes with a bike ride shorter than 100 miles. He has what most would consider an intense and somewhat obsessive personality. If everything goes right, Sunday he will finish three weeks of cycling by logging Mile No. 2,131.61, matching the distance of the Tour de France. Watch Steeber on the road.
